This helps validating DTS files.

Changes that require mentioning:
1. reg-names
   "mspi_regs" and "bspi_regs" were renamed to "mspi" and "bspi" as that
   is what's used in DTS files and in Linux driver
2. interrupt-names
   Names were reordered. "mspi_done" has to go first as it's always
   required.
3. spi-rx-bus-width
   Property description was dropped as it's part of the
   spi-controller.yaml
4. Examples:
   * drop partitions as they are well documented elsewhere
   * regs and interrupts were formatted and reordered to match yaml
   * <0x1c> was replaced with <&gic>
   * "m25p80" node name became "flash"
   * dropped invalid "m25p,fast-read" property
   * dropped undocumented and Linux-unused "clock-names"

This rewritten binding validates cleanly using the  "dt_binding_check".
Some Linux stored DTS files will require reordering regs and interrupts
to make dtbs_check happy.

Commit 60268b0e ("hwmon: (amd_energy) modify the visibility of
the counters") restricted visibility of AMD energy counters to work
around a side-channel attack using energy data to determine which
instructions are executed. The attack is described in 'PLATYPUS:
Software-based Power Side-Channel Attacks on x86'. It relies on quick
and accurate energy readings.

This change made the counters provided by the amd_energy driver
effectively unusable for non-provileged users. However, unprivileged
read access is the whole point of hardware monitoring attributes.

An attempt to remedy the situation by limiting and randomizing access
to chip registers was rejected by AMD. Since the driver is for all
practical purposes unusable, remove it.

Add pmbus driver support for Maxim MAX15301 InTune Automatically
Compensated Digital PoL Controller with Driver and PMBus Telemetry

Even though the specification does not specifically mention it,
extensive empirical testing has revealed that auto-detection of
limit-registers will fail in a random fashion unless the delay
parameter is set to above about 80us. The default delay is set
to 100us to include some safety margin.

This patch is tested on a Flex BMR461 converter module.

These are "all-in-one" CPU liquid coolers that can be monitored and
controlled through a proprietary USB HID protocol.

While the models have differently sized radiators and come with varying
numbers of fans, they are all indistinguishable at the software level.

The driver exposes fan/pump speeds and coolant temperature through the
standard hwmon sysfs interface.

Fan and pump control, while supported by the devices, are not currently
exposed.  The firmware accepts up to 61 trip points per channel
(fan/pump), but the same set of trip temperatures has to be maintained
for both; with pwmX_auto_point_Y_temp attributes, users would need to
maintain this invariant themselves.

Instead, fan and pump control, as well as LED control (which the device
also supports for 9 addressable RGB LEDs on the CPU water block) are
left for existing and already mature user-space tools, which can still
be used alongside the driver, thanks to hidraw.  A link to one, which I
also maintain, is provided in the documentation.

The implementation is based on USB traffic analysis.  It has been
runtime tested on x86_64, both as a built-in driver and as a module.

there's really nothing preventing it from being part of the "real"

Add the newly created regression mailing list finally created after it
already had been agreed on during the maintainers summit 2017 (see
https://lwn.net/Articles/738216/ ). The topic was recently discussed
again, where an idea to create a broader list for all issues was
discussed, but Linus preferred a more targeted list:
https://lkml.kernel.org/r/CAHk-=wgiYqqLzsb9-UpfH+=ktk7ra-2fOsdc_ZJ7WF47wS73CA@mail.gmail.com/

Hence, the creation for that list was asked for and granted:
https://bugzilla.kernel.org/show_bug.cgi?id=212557



In the end it became regressions@lists.linux.dev instead of
linux-regressions@lists.linux.dev as 'Linux' would have been redundant
in the latter case.

During PCH (platform/board) manufacturing process a global platform
reset has to be induced in order for the configuration changes take
the effect upon following platform reset. This is an internal platform
state and is not intended to be used in the regular platform resets.
The setting is exposed via ETR3 (Extended Test Mode Register 3).
After the manufacturing process is completed the register cannot be
written anymore and is hardware locked.
This setting was commonly done by accessing PMC registers via /dev/mem
but due to security concerns /dev/mem access is much more restricted,
hence the reason for exposing this setting via the dedicated sysfs
interface.
To prevent post manufacturing abuse the register is protected
by hardware locking and the file is set to read-only mode via is_visible
handler.

The register in MMIO space is defined for Cannon Lake and newer PCHs.
